what do you mean by leading power factor & lagging power
factor
Answer Posted / simon
Pf is of 3 types i.e
1.Leading (Xc>Xl)
2. Lagging(Xc,Xl)
3.Unity (Xc=Xl)
1.In A.C Circuit if cap Reactance's has more current in comparison of inductive reactance's then Voltage will lead.
2.In A.C Circuit if cap Reactance's has less current in comparison of inductive reactance's then Voltage will lag.
3.In A.C Circuit if both r equal then it will b unity.
